Filed March 4, 1931 Patented Mar. 21, 1933 UNITED STATES nmx VERSTOEP, on THE HAGUE-NETHERLANDS APPARATUS r03. SEPARATING WATER mommepewmamm 6 Application filed March 4; 1931, Serial No. 520,015 and in Ba mn'narjci v', 1930.

The invention consists in air apparatus for continuously separating water from dredged or sucked material, as for instance sand, gravel and like substances.

5 The object of the invention'is to provide an apparatus whereby the dredged material is quickly strained in a receiver and the solid substances are collected and conveyed in movable compartments to a'point of dislG charge, said compartments allowing a further escape of the water which has not been expelled in the first straining action.

The invention will be described with reference to the accompanying drawing.

Fig. 1 is a side elevation of the apparatus with parts broken away; i Fig. 2 is a front view thereof; and

V Fig. 3 is a vertical cross section.

As can be seen from thesefigures, a'sin- 29 gle vertical rotatable wheel 60 has a pluralityv of compartments 61, closed at their lateral sides and also at the outer circumference of said wheel 60, whilst said compartments 61 are open at the inner circum-.

ference of said wheel. 7

The space within the inner circumference of said wheel is used for feeding the dredged material from a delivery pipe 62 into the lowest compartments.

The upper compartments can unload their contents, for instance sand or gravel, on two chutes 63, the upper ends of which are joined and carry a hinged flap 6 1, so that on laying down said flap 64, either the left hand or the right hand chute 63 may serve to discharge the solid material on transporting means of any kind. The flap 64 may be actuated by hand or in any known manner. v

The wheel rests on guiding rollers 65,

a series of such rollers being mounted on the frame plate or on the deck 66 of the dredger, on which is mounted a frame 67 carrying another set of guidingrollers at its top.

The outer circumference of the vertical wheel 60 is fitted with a toothed ring 68 gearing with a toothed wheel 69 driven by the motor 70.

50 A trough 71 with perforated lateral walls for permitting the separated water toflow out ismounted near to the. lowest part of the inner circumference 30f the .vertical A wheel'so' as tol'receivethewet mixture. The bottom of said troughf 71'contains' outlet openings controlled by aSIide'ZQ whichcan be manipulated by the handle 73, 'so that the wet mixture may rest sometime within" said trough so as to drain off the mainpart ofui tswater. As soon as the outlets of said; trough 71 are opened, the solidmaterial al-" though still -mi'xed with some water will fall into the lowest compartments of the ring and Twill then be transported towards the top or upper part. In the 'highe'stposi i tion it will be dumped on the chute 63, after.

having lost nearly all its water through the lateral walls 61? of the compartments 61;

asthese compa'rtments' have gauze covered apertures. P To prevent. the contents of the compart ments from falling out of these compartments during the ascending movement, an 7 endless belt 74 lines the inner circumfer ence of the wheel 60. Said lining belt runs over rollers 75 preferably with the same speed as the inner circumference of the wheel 60. Said belt will be driven either by friction or separately by any known means. Said endles's belt may be ofcourse a metal belt, for instance of gauze The lateral perforated walls 61 of the compartments of the wheel may each be protected on the outer side by a second wall 76 forming-part of he wheel and rotating therewith, so that the lastly expelled water will directly drop towards the bottomportion of the. wheel between the perforated walls 61 and the unperforated walls'7 6 on each side ofthewheel,-the said walls being spaced apart, said space being open along the inner and outer circumferences of the wheel, in order to permit the passageof thej expelled water. V

I claim: a

1. An apparatus for separating water from dredged material, comprising'a wheel 7 structure rotatable about a horizontal axis, said wheel having a series of circumferentially arranged compartmentswhich are open at the side facing the center of the wheel, afixed trough having straining apertures in the side walls mounted inside the wheel in the lowest part of the inner free space, means for discharging the contents of the trough into the wheel compartments, a chute for conveying the contents discharged from the wheel compartme'ntsand extending from the upper part of the inner free space of the wheel to an outer point of discharge, and

means for rotating the wheel.

2. An apparatus for separating water from dredged "material, comprising a Wheel structure rotatable about a horizontal axis, said Wheel having a series of circumferentiallyiarranged compartments which are open at the side facing the center of the wheel and have straining apertures in their side Walls, a fixed trough having straining apertures in theside .Walls mounted inside the wheel in' the lowest part of the inner 'free space, means for discharging the contents of the trough into the wheel compartments, a chute for conveying the contents discharged from the wheel compartments and extending from the upper part ofthe'inner free space of the wheel toan outer point of discharge, a guiding wall arranged for closing the openings of thewheel compartmentsduring their ascending movement towards said. conveying chute, and means for rotating the wheel.
